The Utah Raster Toolkit image file, commonly known as a URT file, is a format used for storing bitmap images. Originating from the Utah Raster Toolkit, a collection of tools and libraries for handling raster images, URT files are specifically designed for complex image processing and visualization tasks. This file format supports various types of image data, including color, grayscale, and black-and-white images. URT files are primarily used in academic, research, and development settings where advanced image manipulation and analysis are required.
A WEBP file is an image saved in the WebP (pronounced "Weppy") raster image format developed by Google for web graphics. It is designed to reduce image file sizes over standard JPEG compression while maintaining the same or similar quality. WEBP files allow images to be downloaded more quickly.
